Answer:
Step-by-step explanation:
Mass m=25 g
Volume V=1.29 cm³
density D=M/V
=25/1.29
≈19.38
≈19 g/cm³

Answer:</h3>
A. 3x² +6
<h3>
Explanation:</h3>
(f-g)(x) = f(x) -g(x) = (4x²+1) -(x²-5) . . . . . substitute the function definitions
... = 4x² +1 -x² +5 . . . . . . . . . . . eliminate parentheses
... = (4-1)x² +(1+5) . . . . . . . . . . . collect like terms
... = 3x² +6
Volume
cube and sphere
the diameter of the sphere=height of box=legnth of box=width of box
volume of cube=side^3
volume of sphere=(4/3)pir^3
side=d=2r
Vcube=d^3
vsphere=(4/3)pi(d/2)^3
Vsphere=(pid^3)/6
percent
basketballV/boxV=( (pid^3)/6)/(d^3)=(pid^3)/(6d^3)=pi/3=aprox 0.523599=52.3599% (round if nececary)
